The principal objects of my invention are to provide a water power intake thatris relatively simple in structure,'capable of be ing easily and cheaply produced and installed and which requires practically no attention after having been placed in position for'use. 1

Further objects of my invention are to construct the intake so that the main body portion thereof, that is positioned within the water has the desired degreeof buoy- I ancy and, further, to provide the. intake with simple and 'eificient means for causing it to maintain a steady position within the stream.

lVith the foregoing andother objects in view, my invention consists in certain novel features of construction andarrangement of parts that will be hereinafter more fully described and claimed and illustrated in theaccompanying drawings in which Fig.1 is a top plan view of a water power able sheet metal, of any desired 'diamsv eter and length andvthe outer end of this tubular body or the'end that is positioned in the running water is flared outwardly so as to provide a funnel-sha ed mouth 11.

In order to prevent dri t wood and like foreign-objects from entering the tubular body, the opening into the flaring mouth 11 .may be mesh. I v To give that portion: of the; body of the intake, that projects outwardly into'the running water, the necessary buoyancy, an air chamber v13, of suitable size is formed on provided with a screen 12 of suitable i tend torings or ection "taken y the ufldersideofbodyj tapered outen 1T0 assist thebody maintaining zsteady position in the water, horizontally disposed,ylongitudina'lly extendingfins or vanes lt are secured to the sides of said bodyv tionedlfor use, occupiesan angular position 7 in a substantially horizontal plane-adjacent to a w'all of concrete {or-masonry W that i a built at or near the bank of the stream, and arranged substantially parallel therewith.

The'intake is'anchor'ed to fthe'wall Win any suitable manner, preferably by means A of chains or cables 15, that are connected to saidintake-at suitable points and which ex-v. posts 16 that'are seated in said wall;

The inner end of thebody 10 of the intake extends into a tubular member 17 that exftendsthrough and occupies'an inclined position in a horizontal plane in wall W. Y

'The fit'or bearingiof the end of'intake 10 initubular member 17 is such, that said intake, under certain stresses,'may slide or rotate wlthin said member 1 Tubular member 17 is directly. connected to a' turbine or water wheel (not shown) and suitably located in said 'member is a gate valve 18 that may be manipulated to controlthe flow of water through the intake and to the turbine. p 7

As illustrated in Figs. 1' and 2, the intake I occupies a practically horizontal plane and projects from the wall W up stream and outwardly toward the center thereof.

' When the 'intakeis positioned in a suit-- ably running stream and the valve '18 is opened, a practically constant volume of water flows into and through said intake and the hydraulic force and power ofthis confined volume flow is deliveredto the turbineto operate same and produce mechanical energy that may be utilized as desired; I

Obviously, a plurality ofthe intakes may be arranged adjacent to a wall, thereby producing, at one station or plant, a relatively large amount of power. V 1 To, prevent floating objects,isuch as logs and'large pieces of ice from striking the flaring screened end of the intake, an inclined deflector plate may be suitablyanso The body-10 of the intake, when posi-;-

V tubular member, having a, flaring monthat; one end, means for anch'oring -rsald tubular chored or positionedin the stream a short V tire length thereof for renderlng the same distance in front of said screened end;

A Water power intake of my mproved construction is] relatively simple requires practically no attention after installation and is very effective in performingits intended functions; e

It will be understood that ininor changes in the size, form and construction of the arious parts of my improved waterf'power intake may be made and, substituted for those-herein described ithout departing; 7 from'the splrlt of tilClIlVGIltlOll, the scope of whlehis set'forth in the appended-claims.

I claim as my invention:

1. A Water power intake comprising a member ina flowing stream at 1 an angle relative to the direction e-rnm of Water in rsai d st'reain and therebeing-an air Chamber formed on the unders de of said tubular member and extending substantially the eng I buoyant.
